Type Name Description
String arg

A string value that represents any information that needs to be sent to the server-side event.

Action<String> onSuccess

A client action to perform if the server round-trip completed successfully.


Use the PerformCallback method if you need to asynchronously go to the server and perform server-side processing using AJAX-based callback technology. You can pass the required information which can be collected on the client side as a string of arguments using the PerformCallback method args parameter. The onSuccess parameter allows you to specify a client function that should be executed after the server round-trip completed successfully.
